Clinton toured the DART Central Station in downtown Des Moines on Monday morning.

"You have already moved past the old false choice between protecting the environment and growing the economy. Instead, you are thriving by doing both. Iowa is leading the nation when it comes to wind energy," said Clinton.

The station uses clean energy systems for heating and cooling.

Clinton made it clear she believes that climate change is an urgent threat to our country and at the same time it is also offering opportunities to make changes now that will lead this country toward a clean energy future.

She said the United states has to show the way and lead by example when it comes to reducing carbon emissions.

Clinton said she has listened to the scientists when it comes to the unforgiving reality of climate change.

Clinton said one of her goals when she becomes president is to set a 10-year goal of generating enough renewable to power every home in America. She said she wants to make America the worlds clean energy super power.
